Description

  The present invention is an improvement of a clamp used for a travel barricade installed at a construction site or the like, more specifically, a barricade that can securely hold a pole with a simple structure and can be easily attached and detached. It relates to a clamp for use.

  As is well known, at road construction work and construction work sites, a mobile barricade that can prevent access is temporarily installed to clearly show off-limits areas in order to prevent danger and prevent outsiders from entering. The measures are taken.

  By the way, since this type of barricade is difficult to fall down with a single impact, a hurdle-shaped frame formed by welding steel is generally used. Therefore, the conventional barricade for construction is heavy and bulky, so it is very inconvenient to transport, store and store.

  Under these circumstances, a barricade of an on-site assembly system that can assemble and disassemble a horizontal member such as a pole into a pair of support legs has been proposed. In such a conventional barricade, the support leg and the pole are When fixing, a connecting member such as a clamp was separately provided.

  However, such a connecting member is very troublesome because the fastening bolt must be tightened or loosened every time the pole is attached or detached, and this connecting member breaks down during repeated use. As a result, the pole could not be fixed and the entire barricade would not function.

  Therefore, the present applicant has invented a barricade support leg in which a clamp is formed integrally with the barricade support leg and has been registered (see Patent Document 1).

  Such a barricade has an excellent effect in that it is easy to use because it is not necessary to tighten or loosen the fastening bolt in the clamp to fix the pole, but the pole falls in the work of attaching and detaching the pole. There is a fear that there is a problem that it is troublesome for the worker to pay attention to handling.
